Immune responses in Mycoplasma pneumoniae infection of infant mouse and of man.

Infant mice (2 to 4 days old) were exposed to living Mycoplasma pneumoniae. The organisms were isolated in the order of 10(3) to 10(4) colony-forming units from the lungs of mice for 2 weeks after infection. Mononuclear cell infiltration was present in the lungs of infected mice.

Protective effect of colostrum in Mycoplasma pneumoniae infection induced in infant mice.

The immunological responses and mechanism of maternal immunity in Mycoplasma pneumoniae infection of mice were investigated. ICR female mice, 4 weeks old, and infant mice, 2 to 4 days old, were infected with M. pneumoniae.

Clinical complications of Mycoplasma pneumoniae disease--central nervous system.

The mechanism of the neurologic complications associated with primary atypical pneumonia is unknown. To examine the ability of Mycoplasma pneumoniae to enter the brain of experimental animals, the organism was inoculated into adult and suckling mice by various routes. After intranasal infection, M.

[Studies on the absorption and excretion of doxycycline for intravenous use (author's transl)].

The absorption and excretion of a new doxycycline solution for intravenous use (DOTC iv) were studied with the following results. 1. Serum levels following one shot intravenous injection of DOTC iv in glucose solution showed a good dose-response comparable with that of the same dose injection of pyrrolidinomethyltetracycline (PRM-TC).
